New materials and manufacturing processes
Development of steels with improved properties
Ceit has an important activity in the optimization of manufacturing processes for improved steels and superalloys for energy applications:
• Microstructural control for improved material performance under harsh service conditions: high temperature applications, deep/sour oil and gas wells…
• Microstructure / property relationships
• Degradation and failure mechanisms: Aging, oxidation, creep, corrosion,… Cyclic conditions and overlapping of mechanisms: thermomechanical fatigue, creep-fatigue. Temperature gradients and thermal shock, wear, radiation. Mechanical properties.
• Surface treatments (i.e. shot peening). Investigation of surface reactions and mechanisms at high temperature
• Modeling
• Bimetallic bonding and production of components through: thermomechanical processes, hot-pressing, HIP and high vacuum furnaces.
• Hot Isostatic Pressure (HIP) for powder consolidation: atomization, can design and manufacture, HIP, final machining. Alternative to Forging+Machining.
